Answer is a right triangle. The angles of a triangle must add to 180 degrees.
You have two 45 degree angles
45 + 45= 90
Now you need 1 more angle to equal 180
180- 90= 90
A right angle is 90 degrees. A right triangle has one right angle and two acute.

Answer: The answer is 314.28 cm² (approx.).
Step-by-step explanation: Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.
We need to find the area 'A' of the circular cross-section of the pipe.
Given, diameter of the circular section is

So, the radius of the circular cross-section will be

Therefore, cross-sectional area of the pipe is

Thus, the answer is 314.28 cm² (approx.).
Answer:
$48,739.50
Step-by-step explanation:
You are going to want to use the simple interest formula for this.

<em>P = principal amount
</em>
<em>r = interest rate (decimal form)
</em>
<em>t = time (years)</em>
<em />
First convert 4.5% into its decimal form:
4.5% ->
-> 0.045
Next, we need to change 120 months into years:

<em>(10 years)</em>
<em />
Now, plug in the values into the equation:


The interest earned after 120 months was $48,739.50
